Math Problem Statement

Which statement correctly describes the relationship between the graph of f(x) and the graph of g(x) = f(x) - 1?

Solution

The problem asks about the relationship between the graph of f(x)f(x) and g(x)=f(x)1g(x) = f(x) - 1.

Solution:

  • When a constant is subtracted from the function f(x)f(x), like f(x)1f(x) - 1, this corresponds to a vertical shift downward by 1 unit.
    • Subtracting a constant affects the y-values of the graph, moving the entire graph downward without changing the x-values.

Thus, the correct option is:

"The graph of g(x)g(x) is the graph of f(x)f(x) translated 1 unit down."


Would you like further explanation or have any other questions?

Here are five related questions you might find helpful:

  1. What happens when you add a constant to a function, like f(x)+2f(x) + 2?
  2. How does translating a graph horizontally differ from vertical translations?
  3. What is the effect of multiplying a function by a negative constant?
  4. How can you identify transformations (shifts, stretches) just by looking at a function?
  5. Can you give an example of a horizontal translation, and how it affects the graph?

Tip: A vertical translation changes only the y-values, while a horizontal shift affects the x-values.
